Applied at Phillips Medisize for Unknown

I recently received a job offer from Phillips Medisize, but the email requesting my personal information seemed suspicious. The contact email was phillipmedisize@post.com, which raised a red flag for me. I did some research on the name and the person who contacted me, and they both appeared legitimate on LinkedIn. However, I still feel uneasy about the situation. I reached out to some friends for advice, and many suggested that it’s likely a scam since legitimate companies typically wouldn’t use a .post email domain for such communications. They also pointed out that background checks usually happen after an offer is made, not before. I'm torn between wanting to pursue this opportunity and being cautious about potential fraud.
